hey everybody! So I am wondering if anyone has any good tricks to get at some of these flame sensors on the high efficency equip? IE: bryant 90+ models or the Lennox model with the rubber Tee for the venting that s in the way?

There has got to be an easy way to clean these things! i have a flex shaft and a small right angle driver attachment that helps but it can still be a pain! Whoot! 15 posts!!

On the lennox units I found for me it is best the take out the rubber tee and use a socket but others may disagree

Sometimes you have to take the gas line apart, too. I hate that furnace!

this is our mfr, so we see a lot of these.

we always b!tch out the rep when they bring out the new units like this.

easiest is as stated, remove boot and sometimes gas line.

come across a couple of the Carriers, one left and one right vented. the right vented was okay, but the left vented was next to impossible. also, the downflows are not fun either. one on our maintenance program and I have skipped doing FS on it, luckily others have come in between my visits. hope they did it.:whistle::whistle:

Ha! try replacing the ignitor when the intake is on the right side!

Did that today. Only using a flexshaft driver. I think I have to agree removing the boot is the easiest. I tend to put a cloth in the ventor opening as I once dropped a screw in there, bad scene!

Ouch! Ya I can imagine that would suck a lot!

On the Bryant/carriers I try to either remove the screw and move the intake or I just use a flashlight and either the Milwaukee right angle driver attachment or a flexshaft attachment and a lot of patience!! wish they would design these things with some mind to service too!

You got that right, I had to change one on a horizontal installation where the vent pipe exited out what would be the right side, and to add insult to injury it was suspended to the ceiling in a garage so I had to do it from a ladder. :gah:

Carrier / Bryant sucks. Engineers have no idea what service guy's have to go thru. 40,000 btu you have to pull intake. Love when the installers silycone fitting. :gah::gah::gah:

Someone told me once, and I would like someone to back up the claim, that Bryant over-engineered the flame sensors so that they expand when heated and will self clean. Since I don't have any concrete answer to this I keep cleaning them. I would LOVE for him to be right though!
